To all whom it may concern:

Be it known that I, EDWIN J. Amw srnono, a citizen of the United States,residing at Erie, in the county of Erie and State of,

a to a steam shovel in which is used a hoisting engine, swinging engineand crowding engine; These engines are used intermittently some of thetime, simultaneously and some of the time independently. 4

The object of the invention is to simplify the lubrication of aplurality of engines receiving their steam from a common supply.

The invention is illustrated in the accompanying drawings as followsFigure lis a plan view of a shovel. Fig. 2'

1 marks the shovel frame, 2 the axle, '3 the supporting Wheels, 4 theswinging table, 4 the boiler, 5 the boom, 6 the hoisting engine, 7 thesteam pipe connecting the boiler with the controlling valve chest 8 fromwhich steam is distributed to the hoisting engine, 9 the steam chests ofthe hoisting engines, 10 the swinging engine, 11 the steam chest of theswinging engine, 12 a pipe for supplying steam to the steam chest of theswinging engine, 13 branches from the pipe 12, connecting the pie 12with the steam chest of the hoisting engine, and 14 a steam pipe leadingfrom the pipe 12 by way of the joint 15 along the boom 5 to the steamchest 16 of the crowding engine 17. The hoisting en gine; operates agear "18 which meshesthe drum gear 19.- The drum gear is carried by drum21is arranged on the shaft20 and operates in the usual manner. A gear 22is arranged on'the shaft 20 and meshes a gear 23 on the shaft 24. Abeveled gear 25 is fixed onthe shaft 24 and drives a ,gear26.

The gear 26 is arranged on the shaft'27 at the axis of the turn table. Aconnection is made With the shaft 27 for driving 'the' wheels of theshovel soas to permit of the a shaft 20 in the frame 6 of the engine.The

movement of the shovel from one placeto 7 another under its own, power.When the hoisting engine is not being used for this purpose the drivingmechanism is "thrown out of action by means of the clutch 20". Theswinging engine drives a beveled gear 28. This meshes ajg ear '29 on theshaft '30.

Thetable 4 is swung through the movement of the shaft in'the usualmanner. :The crowding engine 17 drives a gear '31'on the crank shaft 32.The gear 31; drives a gear 33. The. gear 33 is arranged on ashaft 34 andthe gears 35 are arranged on the shaft 34 and are adapted to operatethe. dipper stick (not shoWn)., The steamengines in a general wayoperate in the usual manner and the several -engi-ne'sperform theirusual functions, f 1

[The hoisting engines have the cylinders 36 (see 7). {These.areconnected with the steamchests 9 ,by'the ports '37. Steam pas- 7sages 3'8 and 39 also lead to the valve surface of the steam chest 9. tThe passages 38 and 39 are connected with the passages 40 and '41respectively the passage plate 8?. Thepassages 4'0 and'41 are connectedby the ports 42 and 43 respectively with, the;

controlling chest 8.": The engine valve 44fis of the usual type and hasthe valve port 45 adapted'to couple the passage 38 with either of theports 37 in the operation of the engine and also the port 46adaptedtocouple the ports 37 with the passage 39'. Steam is introducedthrough one of the passages 38 or 39 and exhausted from the other. Byreversing the flow of steam in these passages, the engine may bereversed. This is a common method of accomplishing this in engines ofthis type. Thevalve 44 is driven through the ,valve rod .47 Thecontrollingv valve 48 i has the valve passage 49 adapted to coupleeither the part 42 or 43 with the exhaust port 50. The exhaust port isconnected with the exhaust passage 51. The controlling valve as operatesbetween the side walls 52 making a rather loose fit withsaid walls.Leading from these side walls are the passages 53 in the passage plate8. These passages 53 connect with the passages 54 leading to the steamchest. The purpose of the steam delivered through the passages 53 to thehoisting engine is to hold the valve 44 to its seat. Steam, therefore,is in the passages 53 at all times when the steam is on the controllingchest. Steam is delivered to the controlling chest through the steampipe 55.

The valve athas the opening 56 in its rear face and is also open at thesides so that steam may at all times pass from the controllingvalve-chest tothe passages 53. A nipple 57 extends through the wall ofthe valve chest and into the opening 56 in position to deliver alubricant on the interior of the valve 44:. The nipple 57 is connectedby a pipe 58 with an oil pump 59 (see Fig. 2). The pump is of ordinaryconstruction being driven through a rock shaft 60. A rock arm 61 isarranged on the rock shaft 60. A link 62 connects the rock arm with apin 63 on the valve rod 47. The valve rod has the pin 64. An eccentricrod 65 extends from the pin 64; to the eccentric 66 on the crank shaft67 of the hoisting engine 6.

Oil is delivered at all times during the operation of the pump. With asteam shovel this is intermittently so that there is more or less oil atthe interior of the valve at all times. There is no passage of steampractically through the passages 53 except when either the crowding orswinging engine is operated. There is, therefore, a pulsation of steamthrough the joint between the valve 44 and the side walls 52 and alsoaround the ends of said valve as the hoisting engine is operated. Thisis sufficient to deliver a proper amount of lubricant from this sourceto the hoisting engine. It also prevents too great an accumulation oflubricant in the passages 53-53. When either the swinging or crowdingengine is started steam passes through the passages 53 carrying with itthe lubricant. This lubricant is carried through the valve chest 9 ofthe hoisting engine, thus leaving some of the lubricant in the chest forthis valve in addition to what is carried to this chest with the steamgoing to the hoisting engine. The lubricant is carried with the steam tothe swinging or crowding engine. In this way a' single lubricating pumpinsures a perfect lubrication of all three engines.
